GRATE.

SPECIFICATION forming part of Letters Patent No. 494,462, dated March28, 1893. Application filed July 21, 1892. Serial No. 440,719. (Nomodel.)

To all whom it may concern.-

Be it known that I, BENJAMIN FRANKLIN GHOLLAR, of Fort Worth, in thecounty of Tarrant and State of Texas, have invented certain new anduseful Improvements in Grates; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to an improvement in grates: and it consists in thenovel feaures of construction which will be fully described hereinafter,and more especially referred to in the claims at the end of thisspecification.

The object of my invention is to construct a grate which is adapted foruse in stoves as well as in fire plaees, and which, being composed ofseparate bars, may be repaired by inserting new bars, thus saving thatportion of the grate which remains intact, as cannot be done with gratesformed of asingle casting.

Referring to the accompanying drawings,-

Figure 1 is a perspective view of my improved grate. Fig. 2 is a view ofthe bars detached or separated. Fig. 3illustrates a slight modification.

The bars A, forming the grate are bent or curved as shown to conform tothe curvature of the front of the fire box or fire place. Upon one sideof the upper end of each of the bars is the angular flange B, againstwhich the next adjacent bar bears thus holding them at this point thedesired distance apart. he outer edge of this flange B, is formed with alongitudinal depression 0, into which projects the bulge D, of the nextbar. By this means the bars are held in the correct relative position.For clamping them together at this point openings E, are formed near thebar ends which are in line and extending therethrough is the bolt F,which holds them most securely together. When the grate is being used ina fire place it may be held up in position by any suitable supportsecured to the bolt ends. At the lower or inner ends of the barsrecessed eyes G,are formed which project to one side as shown andagainst which the respective adjacent bars bear. Throu h these eyesextends the lower clamping boIt H. The outer ends of these eyes arereamed out as shown at H where they fit over the correspondingprojections I, on the sides of the bars A. By means of this interlockingfeature just described together with the depression 0, and the bulge D,at the opposite end of the bars the same are made substantially into onesolid piece, thus relieving the bolts of much of the weight and strain.Bars may also be formed straight as shown in Fig. 3 with the recessedprojections both on the same side of the bar. These are for use inconstructing flat grates for cooking and other stoves incontradistinction to the grate illustrated in Fig. 1 which is adapted toopen front stoves and fire places. Thus it will be seen that a mostsubstantial grate is provided formed wholly of separable bars any one ofwhich may be removed at any time and a new one inserted with thegreatest ease.

Having thus described my invention, I claim- 1. A grate composed of theseparable bars A, each bar formed integral and having transverseopenings at both ends to receive the horizontal clamping bolts holdingthe bars together, the bars being formed at both ends with lateralprojections and depressions to interlock and prevent twisting or warpingof the bars, one side of an end of each bar having the lateral tube Gintegral therewith and countersunk at its outer end and the other sideof said end having the raised boss I to fit the countersunk end of thetube of the next bar, as shown and described.

2. The grate composed of the bent bars, each bar being formed integralwith the lateral tube at one end so that all the tubes of the barsregister, a rod passed therethrough to clamp the bars together, theopposite end of each bar having the lateral angular flange 1), the edgesof the bars and flanges having corresponding depressions and bulges tointermesh, perforated lugs on the bars, and a clamping bar passedthrough the same, substantially as shown and described.

In testimony whereof Iaffix my signature in presence of two witnesses.

BENJAMIN FRANKLIN CHOLLAR.
